.SH NAME
std::chrono::time_point::max \- std::chrono::time_point::max

.SH Synopsis
   static constexpr time_point max();           \fI(until C++20)\fP
   static constexpr time_point max() noexcept;  \fI(since C++20)\fP

   Returns a time_point with the largest possible duration, i.e.
   time_point(std::chrono::duration::max()).

.SH Parameters

   \fI(none)\fP

.SH Return value

   The largest possible time_point.

.SH Example


// Run this code

 #include <chrono>
 #include <iostream>
 #include <vector>

 int main()
 {
     std::chrono::time_point<std::chrono::system_clock> now =
         std::chrono::system_clock::now();
     std::vector<std::chrono::time_point<std::chrono::system_clock>> times
     {
         now - std::chrono::hours(24),
         now - std::chrono::hours(48),
         now + std::chrono::hours(24)
     };

     std::chrono::time_point<std::chrono::system_clock> earliest =
         std::chrono::time_point<std::chrono::system_clock>::max();

     std::cout << "all times:\\n";
     for (const auto& time : times)
     {
         std::time_t t = std::chrono::system_clock::to_time_t(time);
         std::cout << std::ctime(&t);

         if (time < earliest)
             earliest = time;
     }

     std::time_t t = std::chrono::system_clock::to_time_t(earliest);
     std::cout << "earliest:\\n" << std::ctime(&t);
 }

 all times:
 Sun Oct  7 19:06:48 2012
 Sat Oct  6 19:06:48 2012
 Tue Oct  9 19:06:48 2012
